Re: several quick questions

  Hi,

  now from the simple Cogito's point of view. I will swap the two parts
of your mail.

Dear diary, on Tue, Feb 14, 2006 at 05:28:34PM CET, I got a letter
where Nicolas Vilz 'niv' [off-list ref] said that...

And another thing, is there no posibility to get back to some commits or
tags? I realized you can rebranch tags... what, if i want to switch back
to git version 1.1.6 in the git repository? Or a certain commit?

do you have to make a new private branch out of the tag 1.1.6?

i used svn and there i could go back some revisions. I haven't found
such a feature in git, yet... but i think i am blind all the time.

  The simple answer is cg-seek, which is meant for temporary ventures to
the commit history - e.g. you want to go back to git version 1.1.6, but
intend to do no development on top of it and to return back to the top
later. cg-seek will remember "where you came from" and by doing either
cg-reset or simply calling cg-seek without any parameters, it will
return back to the top.

  If you want to permanently change your branch to point to the 1.1.6
tag, the command to use is cg-switch -f. There is also a simpler but
less powerful variant of this command available as cg-admin-uncommit.

i wonder, how i revoke a straight forward merge of two trees... I

I like git very much and every new day I like it more.
actually wanted to be look like somewhere in the git-repository, where
some branches are merged back with the master tree, but i think, that
wasn't "cg-merge -c <tree to merge with the actual one>"...

my result was that my master tree has now the same sha1-sum as my
development-tree and gitk visualisation differs from that what i saw in
the git-repository. (Several Arrows headed into back into one line...)

maybe that was because i didn't do anything in my master tree in the
meantime.

  So I assume that it made a fast-forward merge and you want to undo it.
Unfortunately, there is no facility to automatically remember what your
previous last commit was, so you either:

  * Remember the "fast-forwarding" message cg-merge gave you. ;-)
  * Fire up cg-log and find the commit you want to go back to.

  Now, when you have the commit id, this is the time for cg-switch -f -
what you want to do is to "repoint" your current branch (let's assume it
is master) to the commit id you've just found:

	cg-switch -f -r commit_id master

  (The same thing could be done using cg-admin-uncommit, but it is a
little confusing in this particular usage; you would have to rather
choose the commit id of the last commit to uncommit, and it does not
cope well with merges.)
